That looks like a Cavagnolo accordion keyboard. They used to make a MIDI controller just like that. Never saw one attached to a synth like this though. Where did you find the pic? France? I guess it would be easy to build something like that from scratch, it's just switches. Maybe that is what this is, a one off.

Funny you posted this today. This moning I was thinking about how to convert a cheap midi keyboard controller into a harmonic table controller. The only one on the market that I could find is out of my price range for a controller http://www.c-thru-music.com/cgi/?page=prod_axis-64
